A student was given the task of titrating a 20.
as given the task of titrating a 20. mL sample of 0.10 M HCl(aq) with
0.10 M NaOH(aq). The HCl(aq) was placed in an Erlenmeyer flask. An e
(aq) was placed in an Erlenmeyer flask. An equation for the
reaction that occurs during the titration is given above.

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
